What about a number like 21,003?Where zeros are in between the numbers.

@TiteNYC I had a physics professor (who was brilliant, but couldn't teach his way out of a paper bag) who told us on the first day that if we weren't physics or engineering majors, we would fail the class. Came as a surprise to us chemistry, biology and earth science people who needed it as a graduation requirement. Knowledge is treated by some like a commodity that is precious and should only be shared with those who deserve it. I believe knowledge is free and should be shared with everyone.

I personally thank you SO MUCH!!!! I have a test tomorrow and the teacher subscribed JACK!!!! We were asking questions and she was acting like she didn't see them at all!!!! Jesus what has this nation's education come to!!! I need t pass...My future depends on this teacher and she is acting like chemistry isnt important!!!! WTF!!!! Thnx again!!! Im glad there are still teachers that can actually teach in this world!!! ^^

It is 4:05 am and I have an exam at 9:30. I have learned more from watching several of these videos than from my chem teacher in the entire quarter. My teacher got a ph.d in chemistry from MIT that she brags about, I say that it is worthless if she can't teach and use it. Mark you really do a great job clarifying things up. This all nighter will go on

I spent about four months putting together these tutorial videos. I will be coming out with new ones using narrated Powerpoints in the near future. They take a huge amount of time to do right, though. We'll see, maybe in the fall.

I feel like now we just learn "how" to do certain things, but we don't understand "why" we do it that way anymore. Ohh wells, I hope I pass my Chem quiz tomorrow which my teacher calls it a "quest" cause of her accent. :X

Thank-you Mark for helping me with this and your other chemistry videos! I am a 51 year old student, taking chemistry, kicking and screaming the whole way! I will keep watching and keep studying.

My teacher recommended my chemistry class to your videos cause she's lazy and doesn't know how to teach. Honestly she could eat a limp wiener. Anyway, THANKS FOR THE VIDEO MAH NIGGUH.

wow, that explains it a whole lot better than my teacher could ever do! thanks! btw, how long did it take for MarkRosengarten to make all of these videos? just curious...

Thank you so much sir. I wish you would come and teach at my school, my high school chem teacher doesn't know how to teach and doesn't even care if we fail or not.

Great video, thank-you for this and your other chemistry videos. I am a 51 year old student trying to pass Gen Chemistry, and I really appreciate the help!

REALLY helped me notice how to put additional digits by the sig figs because - for lack of original reason - of my confusing teacher.
